I'm trying to get ltsp going on gentoo, but there is apparently no longer an "ltsp" ebuild. I found one guide that said you had to use an ltsp overlay (layman -a ltsp), so i installed git and did the layman -a command without errors, but still there is no "ltsp" or "ltsp-server" ebuild. Is there another way to get ltsp going? Anyone possibly know of a gentoo based distro that installs w/ ltsp already installed?

ltsp is a git overlay. If your checkout worked, properly you should have a directory like:

/usr/local/portage/layman/ltsp

All of the ebuilds for that overlay will be there. The ltsp-server ebuild is ~ keyworded. If you are running stable, you will have to add the ltsp to your package.keywords to get portage to show the ebuild in an emerge.
